DETAILED DESCRIPTION

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 4 As shown, a promotion and display device for technology promotion provided by an embodiment of the utility model includes a promotion and display screen 1 and a cleaning plate 2. The cleaning plate 2 is arranged on the front side of the promotion and display screen 1. Cleaning cotton 3 is arranged on the rear side of the cleaning plate 2. The surface of the cleaning cotton 3 is in close contact with the surface of the promotion and display screen 1. A device shell 4 is fixedly connected to the rear side of the promotion and display screen 1. The inner cavity of the device shell 4 is movably connected to a control frame 5. The bottom of the control frame 5 penetrates the device shell 4 and extends to the outside of the inner cavity of the device shell 4. A limiting device 6 is arranged inside the device shell 4.

[0023] refer to Figure 4 The limiting device 6 includes two limiting shells 601, and the opposite sides of the two limiting shells 601 penetrate the device shell 4 and extend to the outside of the inner cavity of the device shell 4. The top and bottom of the inner cavity of the device shell 4 are fixedly connected with two stabilizing rods 602 used in conjunction with the limiting shells 601. The surface of the stabilizing rods 602 contacts the inner cavity of the limiting shell 601. The opposite sides of the two limiting shells 601 are fixedly connected with springs 603, and the opposite sides of the two springs 603 are fixedly connected to the inner cavity of the device shell 4.

[0024] By adopting the above solution, by setting the limiting device 6, when the cleaning plate 2 and the cleaning cotton 3 are used up, the limiting device 6 can limit the position of the cleaning plate 2 and the cleaning cotton 3.

[0025] refer to Figure 4 The front side of the limiting shell 601 is fixedly connected to the extrusion rod 7, and the right side of the control frame 5 is fixedly connected to the extrusion block 14 used in conjunction with the extrusion rod 7, and the surface of the extrusion block 14 contacts the surface of the extrusion rod 7.

[0026] The above solution is adopted: by providing the extrusion rods 7, when the two extrusion rods 7 are subjected to the extrusion force of the extrusion block 14, they will move to the side away from each other, and when the extrusion rods 7 move, the limiting shell 601 can be driven to move.

[0027] refer to Figure 4 The right side of the extrusion block 14 is fixedly connected to the outer shell 8 , the inner cavity of the outer shell 8 is movably connected to the inner shell 9 , and the right side of the inner shell 9 is fixedly connected to the inner cavity of the device shell 4 .

[0028] The above solution is adopted: by setting the outer shell 8 and the inner shell 9, when the extrusion block 14 moves, the outer shell 8 can be driven to move along the surface of the inner shell 9. The coordinated use of the outer shell 8 and the inner shell 9 has a limiting effect on the moving position of the extrusion block 14.

[0029] refer to Figure 3The inner cavity of the device shell 4 is movably connected with a baffle 10 , and both sides of the baffle 10 away from the limiting shell 601 penetrate the device shell 4 and extend to the outside of the inner cavity of the device shell 4 .

[0030] The above solution is adopted: by setting the baffle 10, the setting of the baffle 10 has a limiting effect on the position of the roller 12, so that the roller 12 is in a fixed state when not in use.

[0031] refer to Figure 5 The top and bottom of the baffle 10 are both provided with limiting grooves 11 used in conjunction with the limiting shell 601 , and the surface of the limiting shell 601 is in contact with the inner cavity of the limiting groove 11 .

[0032] The above scheme is adopted: by setting the limit groove 11, when the baffle 10 rotates to the position in contact with the surface of the roller 12, the control frame 5 is released, and the restoring force generated by the spring 603 restoring its shape will drive the limit shell 601 to be stuck into the inner cavity of the limit groove 11. The coordinated use of the limit shell 601 and the limit groove 11 has a limiting effect on the position of the baffle 10.

[0033] refer to Figure 2 The left and right sides of the cleaning plate 2 are fixedly connected with rollers 12, and the left and right sides of the promotion display screen 1 are provided with roller grooves 13 used in conjunction with the rollers 12. The surface of the roller 12 is movably connected to the inner cavity of the roller groove 13, and the top of the baffle 10 is in contact with the bottom of the roller 12.

[0034] The above scheme is adopted: by setting the roller 12 and the roller groove 13, when the cleaning plate 2 moves, the roller 12 will be driven to move along the inner cavity of the roller groove 13. The coordinated use of the roller 12 and the roller groove 13 has a limiting effect on the moving position of the cleaning plate 2 and the cleaning cotton 3.

[0035] The working principle of this utility model:

[0036] When in use, when it is necessary to conveniently clean the promotion display screen 1 used for technology promotion, the user first pulls the control frame 5 to the right. When the control frame 5 moves, it will drive the extrusion block 14 to move along the surface of the extrusion rod 7. When the extrusion block 14 moves, it will drive the outer shell 8 to move along the surface of the inner shell 9. The extrusion rod 7 subjected to the extrusion force will drive the two limit shells 601 to move away from each other along the surface of the stabilizing rod 602. When the limit shell 601 moves, the force generated causes the spring 603 to undergo elastic deformation. When the limit shell 601 moves, the spring 603 is deformed. When the shell 601 is separated from the limiting groove 11 and completely moved to the inner cavity of the device shell 4, the baffle 10 can be rotated backward to drive the baffle 10 to rotate along the inner cavity of the device shell 4. When the baffle 10 is separated from the contact with the pulley surface, the cleaning plate 2 can be moved up and down. The movement of the cleaning plate 2 drives the roller 12 to move up and down along the inner cavity of the roller groove 13, and at the same time drives the cleaning cotton 3 to move closely along the surface of the promotion display screen 1. The cleaning cotton 3 will clean the dust on the surface of the promotion display screen 1. At this time, the promotion display screen 1 used for technology promotion is conveniently cleaned.

[0037] In summary: the promotion and display device for promoting technology solves the problem that there are many existing promotion and display equipment, including display racks, display columns, leaflets and promotion display screens, by setting the limiting device 6, limiting shell 601, stabilizing rod 602, spring 603 and human limiting groove 11. The promotion display screen is a promotional device for promoting by playing promotional videos or pictures. The crowd watching the promotion display screen is relatively complex, and the screen is easily contaminated with more dust and stains. If it is not cleaned in time, it is easy to affect viewing. However, the existing promotion display screen has no components for conveniently cleaning the screen.
